The cam in the video is a hydraulic roller.
Yours is a flat tappet.
You are losing duration to lash. The hydraulic roller is not.
I love reading those magazine articles, they act like the lift is some wampuss-cat sky-high number that's very secretive. I'm not a betting man, but I'd say it's around .600".
On a hydraulic roller with an FE, you have to play the numbers game. You can either use an aggressive lobe that will make noise and not make power, or you can use a less aggressive lobe that will make power, will be quiet, but will have a high advertised duration. When you try to run vacuum accessories with a high advertised duration, you have to widen the LSA to get the overlap down.
Your cam is antiquated, Patrick.
